Self Join in Laravel 5.2 - php

Question

I have the following Ticket Table
if(!Schema::hasTable('tblticket')) {
Schema::create('tblticket', function (Blueprint $table) {
$table->increments('TicketID');
$table->string('Subject', 50);
$table->integer('ParentTicketID')->nullable()->unsigned();
$table->timestamps();
$table->foreign('ParentTicketID')->references('TicketID')->on('tblticket');
});
}
Primary Key is TicketID and There is another column called ParentTicketID, which is related to TicketID.
Below is Ticket Model
class TicketModel extends Model
{
public $table = 'tblticket';
public $primaryKey = 'TicketID';
public $timestamps = true;
public function TicketReplies() {
return $this->belongsTo('\App\Models\TicketModel', 'TicketID');
}
}
Below is my Query
$Ticket = \App\Models\TicketModel
::with('TicketReplies')
->where('ParentTicketID', '=', $TicketID)
->first();
I am trying to get all child tickets of a Ticket. but I am getting null.
Can you please guide if I am missing something.

Answer 1

this is my sample code, you can try this, I hope that will help you
/*---------------------------------------------------------
* Relationship with same table, means recursive key
* --------------------------------------------------------
*/
//this will get the childern against parent.
public function doseage_childs(){
return $this->hasMany('App\Models\DoseageForm', 'parent_id', 'id');
}
//this will get the parent against childern
public function doseage_parent(){
return $this->belongsTo('App\Models\DoseageForm', 'parent_id', 'id');
}
Edited
update your this method
public function TicketReplies() {
return $this->belongsTo('\App\Models\TicketModel', 'TicketID');
}
like this
public function TicketReplies() {
return $this->hasMany('\App\Models\TicketModel','ParentTicketID' ,'TicketID');
}
and update your query model like this, because you already getting TicketReplies relationships.
$Ticket = \App\Models\TicketModel
::with('TicketReplies')
->where('TicketID', '=', $TicketID)
->first();
You relationship will works then
